Specification of Letters Patent.

' Patented July 3, 1906.

,To all zzz/tom, t may concern:

a section of a part of two ears, showing my 2 is a oen-- Be it knownthat I, ALEXANDER W. IRviN,

a citizen of the United Sta-tes, residing at Al` toona, in the county ofBlair and State of ,Pennsylvania, have invented certa-in new and usefulImprovements in Hose-Couplings and I do hereby declare the following tobea lull` Clear, and exact description of the invention, suoli as willenable others skilled in the art to which itv appertains to make and usethe same.

My invention relates to improvements in 'hose-ouplings adapted for usewith the air or steam systems on railway-trains; and the c I)jectof-'umy invention is to produoe a'. device of this-Character lmadeentirely of metal, thus doing away 'with the rubber portions ordinarilyused -in such couplings, which soon deteriorate in actual service, andyet preserving' perfect flexibility.

Vith these objects in view my invention consists in the construction andcombinations of parts, as hereinafter described and laimed.

' In the accompanying drawings, Figure 1 is invention applied thereto.Fig. tral cross-section, partly in elevation, of onehalf of mv improvedcoupling; Fig. a cross-section, on a larger scale, of the balland-socketjoint; and Eig. 4 '.s a cross-section on the line -l 4 of Fig. J3.

(L represents the air or steam pipes, b the angle-cooks, and c the partsof the couplerjoint, all these parts being of the usual eonstruetion. The rubber hose, however, which iusually connects the angle-eoek with thei member to the center of the ball and one or Coupler-joint, is in myinvention replaced by a metal construction designed to have somei f andConnecting with the larger perforatum.

what the functions of a human. arm-that is to say, to permit perfectflexibility within certain limits.

The connection between one of the angle- Coeks, l) and thecorresponding'part c of the coupler-joint is made by means of aball-andsooket joint d, a.v straight pipe e, a bent pipef, anelbow-jouit g, and a bent pipelz. (Shown in section m Fig. 2.) One endof the pipe h is eoned ofi", as shown at i, fitting 'in a similarportion in' the outv.'ardlyflared end of the pipel f.' the whole beingsurrounded by a union-joint y', which permits freedom of movement in oneplane. A packing (not shown) may be employed inside of the unionjointy', if desired.A The ball-andsoeket joint" .consists of two socketmembers lc and Z,

as shown at n, and provided with an internal i screw-thread with whichthe pipe. e'engages,

the construction being sueh that pei-feet freedom of movement isobtained within quite wide limits.' The pipes z, f, and e are 'ofcoursehollow, and the ball member 'm is pro- 4vided with a large perforation oand a series of smaller perforations pi 'll he part la of the socketImember is also perforated, as shown at t, for the passage of air orsteam. 'lhe part is also provided with awlarger perforation r for thereception of a spring s, which bears against the bottom of theperforation r and at the other end bears against a washer t, resting onthe ball member mi, orz if desired, the washer may be madeintegraltherewith.

Itis obvious that eat-h half of'lhe coupling may be moved freelyinanydireetion by means of the ball-and-soeketjoint and that the parts Cof the Coupler-joint may be engaged together in the. usual way by movingthem about the elbow-joints.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States. is-

In a hoseeeoupling the combination with the train-pipes, of couplingstherefor eaeh provided with a ball-andsoeket joint (ronsisting of a ballmember having one large perforation extending from the neck of said moresmaller perforations extending .from

two socket members adapted to iin-lose the ball of said ball member, oneof said starker members containing perforations one adapt-- ed tocontain a springl aspring adapted to press'the ball member away fromoneof the socket members to form an air-passage from the smallerperforations in said ball member through the larger socket member and awasher interposed between said ball `member and said spring,substantially as described. In testimony whereof I allix .my signaturein presence of two witnesses.
